Application filed September 26, 1913.

My invention relates toreceptacles each.

including two plain concentric tubes with corrugated paper between them. As heretofore constructed such receptacles are of two general types, first, a tube formed of spirally wrapped strips and consequently having seams extending transversely with respect to the tube axis from end to end thereof; and second, a tube including two convolutions of corrugated paper so constructed and arranged that their corrugations are held out of mesh with respect to each other.

My invention provides a receptacle adapted for use as a bottle wrapper, including a tube which may be formed without the employment of the spiral winding mechanism which is essential to the formation of said first type of receptacles, and which is more compact and efficient than said second type of receptacles in that the corrugated web constituents thereof are intermeshed.

.As hereinafter described, my invention includes a cylindrical tubular paper receptacle comprising two plain concentric cylindrical tubes with two currugated paper webs between them; the outer and inner tubes being both formed of a single web of plain paper carrying said two corrugated paper webs respectively upon its opposite faces; said two corrugated webs each having their corrugations uniformly spaced,

but so respectively, differently spaced, circumferentially, that the crests of the corrugations of the respective webs intermesh when said webs are wrapped in concentric relation; said outer and inner tubes being respectlvely continuous, without transverse seams, from end to end thereof.

As hereinafter described I prefer to at-. tach said corrugated webs to each other, and to the primarily plane webs which carry them, by means at the crests of the corrugations only; said webs remaining separate from each other between said crests, and, therefore, it is to be noted that such a Specification or'Letters Patent.

Serial No. 792,025. I i I product and process isclaimed in Letters Patent of the United States 1,032,789 granted to me July 16, 1912; the claims of the present case being limited to the construction and arrangement of such a product as a receptacle, and specifically a bottle wrapper.

My invention includes the various novel features of construction and arrangement hereinafter more definitely specified.

In said drawing: Figure I is an end View of a paper receptacle bottle wrapper conveniently embodying my invention in 1ts most complex form, including two corrugated paper webs connected only at the crests of their corrugations and a single plain web carrying both of said-corrugated webs. Fig. 11 is an end view of a papertwo corrugated paper webs connected only at the crests of their corrugations and two plain webs respectively carrying said corrugated webs. Fig. III is a longitudinal sectional view of the form of my invention shown in Fig. I provided with double flanged cap closures at its respectively opposite ends. Fig. IV is an end view of a modified form of my invention including a single plain web forming both the inner and outer concentric plain tubes and carrying a single corrugated web between them. Fig. V is an end View of a modified form of my invention including a single corrugated web between the inner and outer plain cylindrical tubes respectively formed by distinct pieces of paper. Fig. VI is an end view of the fabric employed in the receptacle shown in Fig. I, but in its primarily plane position. Fig. VII is an end view of the fabric employed in the receptacle shown in Fig. II, but in its primarily plane position. Fig. VIII is an end view of the fabric employed in the receptacle shown in Fig. 1V, but in its primarily plane position. Fig. IX is an end view of the fabric employed in tl e receptacle shown in Fig. V, but in its pri.1arily plane position.

Referring to the form of my invention shown in Figs. 1, III and VI; the single plain and primarily plane web 1 is volutely wrapped to form both the outer cylindrical tube 2 and the inner cylindrical tube 3 which are in concentric relation as shown in Fig. I.

Said single web of plain paper 1 carries the two corrugated paper webs 5 and 6 respectively upon its opposite faces, as best shown in Fig. VI, and attached thereto only at the crests of their corrugations. Said two corrugated webs each have their corrugations uniformly spaced but so respectively differently spaced, that thecrests of the corrugations of the respective webs 5 and 6 intermesh when said webs are wrapped in 1 concentric relation; the corrugations .of the Web 5 having a greater circumferential pitch thanthe corrugations of said web 6. It may be observed that the blank portion 8 of said web 1 between said webs 5 and 6, as shown in Fig. VI, connects the outer and inner cylindrical tubes 2 and 3 as shown in Fig. I and that the opposite ends ,9 and 10 of said single web 1 respectively overlap the outer surface of the tube 2 andthe inner surface of the tube 3.

The hollow cylindrical receptacle shown in Fig. I may be used as a wrapper with its opposite ends open; but I prefer to provide it at each end with a closure including cylindrical flanges in integral relation respectively arranged to fit outside of the outer tube and inside of the inner tube. As shown in Fig. III the cap 12 includes the two concentric cylindrical flanges 13 and 14 in unitary relation, being formed of a single piece of paper which is pressed to the shape shown, including the diaphragm 15 extending trans- Versely with respect to the receptacle and closing the end thereof. It may be observed that said diaphragm is so constructed and arranged in its relation with said flange 14 as to resiliently oppose endwise movement of the contents of the receptacle and support said contents in spaced relation with the surface upon which the receptacle rests. The opposite end of said rece tacle shown in Fig. III has the closure cap 1 including two concentric cylindrical flanges 18 and 19, formed of distinct pieces of paper, respectively arranged to fit outside of the outer tube 2 and inside of the inner tube 3 and including diaphragms 20 and 21 extending transversely with respect to the receptacle and closing the end thereof. Said two pieces of paper forming the cap 17 have adhesive means 23 integrally connectingthem. However, it is to be understood that they may be otherwise connected, for instance by a wire staple or eyelet.

In the form of my invention shown in Figs. II and VII; the outer and inner plain cylindrical tubes 25 and 26 are respectively formed :by distinct pieces of paper respectively carrying the corrugated webs 28 and 29 which are attached thereto only at the I crests of their corrugations as shown in Fig.

VII. Said corrugated webs 28 and 29 are of respectively difierent circumferential pitch,

like the webs 5 and6 aforesaid, so that their crests intermesh as shown in Fig. II. I prefer to connect said corrugated webs 28 and 29 only by means at the crests of their corrugations. It may be observed that the end 31 of the plain paper web 25 shown in Fig. VII overlaps the outer surface of the outer tube as shown in Fig. II and that the end 32 of the plain paper web 26 shown in Fig. VII overlaps the inner surface of the inner tube as-shown in Fig. II.

It is to be understood that the receptacle shown in Fig. II may be provided with closure caps at its opposite ends such as shown in Fig. III.

Referring to the form of my invention shown in Figs. IV and VIII the outer and inner plain cylindrical tubes 35 and 36, shown in Fig. IV, are formed by the single plane paper web 37 shown in Fig. VIII which carries the single corrugated web 38 attached thereto only at the crests of its corrugations. It may be observed thatthe end 40 of said plane web 37 shown in Fig. VIII overlaps the outer surface of the outer tube 35 as shown in Fig. IV, and the opposite end 41 of said web 37 shown in Fig. VIII overlaps the inner surface of the inner tube 37 as shown in Fig. IV.- The blank portion 42 of said web 37 connects the outer and inner cylindrical tubes 35 and 36 as shown in Fig. IV.

Referring to the form of my invention shown in Figs. V and IX; the outer and inner cylindrical tubes 45 and 46 are formed by distinct pieces of paper holding between them the single corrugated web 47 which is primarily carried by the plane web 45 shown in Fig. IX and attached theretoonly at the crests "of its corrugations. It may be observed that the end 48 of said web shown in Fig. IX overlaps the outer surface of the outer tube 45 shown in Fig. V, and that the end 50 of the plane web 46 shown in Fig. IX overlaps the inner surface of the inner tube shown in Fig. V.

It is to be understood that both forms of my invention shown respectively in Figs. IV and V may be provided with flanged closure caps such as shown in Fig. III.

It is to be particularly noted that each form of my invention above described may be constructed by merely wrapping the fabric cylindrically, and without seams extending transversely with respect to the axis of the-receptacle, the several seams being parallel with said axis.

I do not desire to limit myself .to the precise details of construction and arrangement herein set forth as it is obvious that various modifications may be made therein without departing from the essential features of my invention as defined in the appended claims.
